About This Product
This heavy-duty diaphragm clutch spring from Alto is designed to provide increased clamping force for 1984 to 1989 Big Twin models. It serves as a high-performance replacement for OEM 37871-84 and 37875-86A. This spring is also a key component in certain diaphragm update kits for 4-speed Big Twin models. If your clutch is starting to slip under load, upgrading to a heavy-duty spring is often the best solution. Alto's manufacturing process ensures consistent spring tension and long-term durability, making it a reliable choice for both stock and mildly modified engines. It is sold individually and is a straightforward upgrade for better power transfer.
Manufacturer part number: 026767.
